The Simpson ECCLLQ444HDG L-Shape End Column Cap is engineered for end-of-beam structural connections where two beams intersect in an "L" formation on top of a column. Designed to accommodate a 4x main beam, 4x post, and 4x side beam, this heavy-duty connector helps distribute load from the beams and provides critical support at the junction point. The side beam is oriented left, making it the right choice for left-hand "L" configurations. Built from 7-gauge steel with a hot-dip galvanized finish and paired with included Strong-Drive SDS Heavy-Duty Connector screws, this column cap is ready to handle demanding exterior and treated-wood applications right out of the box.

Key Features

• SDS screw configuration optimized for uplift loads - screws are positioned to deliver high uplift design values, giving buyers confidence that the connection will perform under real-world vertical and lateral forces.
• Certified welds throughout - weld quality is verified to meet strength and loading standards, so structural integrity is not left to chance.
• Diamond holes for temporary fastening - allows the cap to be held in position during layout and alignment before final fastening, reducing installation errors and saving time on the job.
• Left-oriented side beam design - purpose-built for left-hand "L" beam configurations; the ECCLRQ model is the corresponding option for right-side beam orientation, so buyers can select exactly the geometry their project requires.
• 7-gauge steel construction - heavy-gauge material provides a robust, rigid connector capable of handling substantial structural loads.
• Hot-dip galvanized coating - the HDG finish delivers superior corrosion resistance compared to standard coatings, making this column cap suitable for exterior installations and use with pressure-treated lumber where corrosion protection is required.
• Strong-Drive SDS screws included - installing with the included 1/4 in. x 2-1/2 in. SDS Heavy-Duty Connector screws means faster installation and a lower profile than standard through bolts, with no separate fastener purchase needed.

Why This Product

• A purpose-built solution for L-formation beam connections - rather than adapting a generic bracket, this cap is specifically designed for end-of-beam applications where two beams meet at a column in an "L" layout, generally eliminating the need for additional brackets or braces at that connection point.
• HDG coating handles the toughest exposure conditions - hot-dip galvanization provides a level of corrosion protection that holds up in exterior environments and against the chemicals present in treated lumber, protecting the structural connection over the long term.
• Faster installation without sacrificing strength - the included SDS screw fastening system allows the column cap to go in quicker and with a lower profile than through-bolt alternatives, while still achieving high uplift design values at the connection.
• Backed by Simpson Strong-Tie engineering standards - certified welds and a screw pattern engineered for load performance mean this connector is built to meet the demands of real structural applications, not just light-duty assembly.

Frequently Asked Questions

What beam and post sizes is the ECCLLQ444HDG designed to fit?

This column cap is designed for nominal 4x member sizes - specifically a 4x main beam, 4x post, and 4x side beam. It is intended for end-of-beam applications where two beams meet in an "L" formation on top of a column.

What fasteners are included, and do I need to purchase them separately?

The ECCLLQ444HDG includes 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws (Model: SDS25212). These screws are configured to provide high uplift design values and allow for faster installation with a lower profile compared to standard through bolts, so no separate fastener purchase is needed.

Is this column cap suitable for outdoor and treated-wood applications?

Yes. The ECCLLQ444HDG features a hot-dip galvanized (HDG) finish, which provides extra corrosion resistance making it well suited for exterior environments and use with treated wood.

What is the difference between the ECCLLQ444HDG and the ECCLRQ model?

The ECCLLQ444HDG is oriented with the side beam on the left side. If your project requires the side beam to be oriented on the right side, you should order the ECCLRQ model instead.
